| Summary: | <p>The important Jurassic foraminiferal genus <i>Reinholdella</i> is described and redefined based on the extant holotype of the correct type species, <i>Reinholdella dreheri</i> Brotzen, 1948 (<span class="inline-formula">=</span> <i>Discorbis dreheri</i> Bartenstein sensu ten Dam and Reinhold, 1942). The invalid neotype of <i>Reinholdella dreheri</i> (Bartenstein), erected by Loeblich and Tappan (1987) (that should have been referred to as the neotype of <i>Discorbis dreheri</i> Bartenstein), is illustrated by scanning electron microscope (SEM) photography and redescribed. Some of the taxonomic confusion surrounding the species <i>Discorbis</i> <i>dreheri</i> Bartenstein, 1937 is illustrated from the variable morphotypes in the type material. An important species ascribed to <i>Reinholdella</i>, <i>R. macfadyeni</i> (ten Dam), is illustrated and its features compared with the type specimen. The holotype of the type species and other species illustrated have only one aperture. Species assigned to <i>Reinholdella</i> require re-assessment.</p> |
